Title
A finite element method for two-phase surface fluids and modeling of multicomponent lipid membranes.

Abstract
This talk reviews a continuum-based model for the process of phase separation in  multicomponent lipid membranes exhibiting lateral fluidity. We further introduce a finite element method for solving surface fluid and surface phase-field equations. The models and methods are combined to deliver a finite element method for a thermodynamically consistent  phase-field model for  surface two-phase fluid. A stable linear splitting approach is introduced and available numerical analysis results are presented. We finally discuss successes and failures of the model to reproduce in vitro experiments with multicomponent vesicles of different lipid compositions.
